To all Iwhom t may Gomera.'

Be it known that l, ADAM Posfrnnsnr,

a citizen of 's-"ii, residing;` at T`flillimantic county,Y ot in7 and State et Connectithe' provision of is requiring the ad ji of perm t. Aon elements to permit movement et the leek holt and the iol` lowing; adiustment of apermutation element to actuate the lock holt.'

The invention ejenerally indicated coniprises a loch pj( ng the J. discs to prevent holt, the dises h iery o? pei n oclring movement of the r arrengged in sets and separetel;v contro-.ed according; to a predetermined errangement to arrange radial slots in said discs in line with the holt to permit its movement. Bolt operatingl means are prorit 'which is norm-elly. he

rlhe invention is villustrated in the aecompanying drawings, in which:

[in the drawings, the lock is shown as mounted in ai door l0, the frame ll of which is provided with the usual keeper l2.

The locli proper includes a metallic casing-` havingV side Walls 14k and 15 and a cover Serial No. 245,641.

plate 1G adapted as is usual to extend he vond the casing to permit securing or the lock. as by festeninps i7 n the usual mortise in the edge of the door. Slidabl7 mounted Within the casing; is a locking holt 2l locking lli-.gs 2O projecting at right angles thereto and when in lockingposition extendingtr through the cover plete to engage the keeper.

The lookin holt ffl is formed Within the casing near the respective ends thereo'il with transverse har sections 23 and 24, and these sections are adapted to overlie and heer upon the peripheries of independent sets et discs, the enz'nagement of the leurs with the peripheries of the respective sets ot discs holding' the locking bolt 2l in position to maintain the locking lugs t) in operative or lool-.ringY positions. rllhe respective. sets ot dises are in duplicate, the lower set for example involving an inner disc 2E fined upon spindle 2S supported in a liess 29 projecting trom the side Woll of the casing' and in a sleeve secured to the front Wall of the casing. An intermediate disc 26 and a 'forward disc 27 ere loosely mounted on the sleeve 33 and held in spaced relation hy collars 34. rEhe dises 215, 26, and 27? are formed with radial slots 3'?, 38, and 39 respectively, which e3;- tend through the plripheriesof the disc, and when in alignment transrersel)T of the casing?,` end in register with the projection 24, providing' an opening to permit mmjern Y of said projection 2st and hence the loc.-- ing holt 2i inwardlyq to more the locking lugs 20 to an unlocking' position, assuming` that the upper set of discs has been correspondingh7 arranged. The spindle 28 projects beyond one side Wall et the casing' in the form of an operating knob Si? which may he pr vided with a y po-inter or other indicator tor movement over a dial 30 to determine the positions or the respective discs. Disc 26 is provided with projections 40 extending at ric'ht angles' thereto and adapted to he enga ed by and engage projections 42 from disc 26 and a projection 43 from disc 27, This arrangement provides a simple i'orm ot permutation control ot the discs, and it is oloviousl7 apparent that throuo'h manipulating' the discs through successivei f reversed movements of the knobs 8l, the discs may, at will, be ar ranged to permit movement oit the locking` bolt 21 so far as the projection 24 is inserted. The upper set of discs 25, 26', and 2T', are duplicates of the lower set of discs, the disc 25 being connected to a spindle 28 mounted at one end in a boss 29 projecting from the side wall of the casing and also in a sleeve 33 projecting from the opposite side wall, the spindle extending through said latter side wall and having an operating rod 3l cooperating with the dial rfhis upper set of discs includes discs 26 and 27', the. former provided with projections to cooperate with projections 42 and 43 from the discs 25 and 27 said discs 26 and 27 being loosely mounted on the sleeve 83 and held in spaced relation by collars 34', and said discs 25"` 26', and 27 being formed with radial notches 37', 38, and 39, which when the upper set of discs is operated according to a predetermined movement of the dial, the notches in these discs will be arranged to permit movement of the upper projection 23 of the locking bolt.

Obviously therefore, the locking bolt is normally held against movement when in locking position by the peripheral edges of thejdiscs, and the movement of the locking bolt is permitted only following proper set or arrangement of both the upper and lower set-s of discs.

The means for operating the lock bolt includes arms 45 and 46 projected inwardly from the lock bolt 2l and arranged in spaced relation, being guided in a frame 48 supported by brackets 4 5) projecting from the side wall of thel casing. An operating spindle 57 is mounted for longitudinal sliding movement in ihat side wall of the casing carrying the dials 30 and 30. This spindle has an operating handle 64 adapted for cooperation with a` dial 65 and on the spindle and between the inner' surface of the side wall of the easing and the handle 64 is a coil spring (i8. An open bracket 63 tends to support the shaft and also to limit the inward position of the handle 64, the wall of the casing being formed with an opening of sufcient size to permit the movement of the handle knob (i4 therethrough. Rotatively supported upon' the spindle 57 and held against other than rotative movement in the frame 48 is a gear a. laterally extended operating member 69 preferably in the form of a loop and of a size to readily enter the slots 72 and 7l when the latter are aligned.

Supported in brackets 52, 53, projecting from the inner side wall of the casing is a latch bolt 50,v normally spring pressed in latching position, that is, with its nose beyond the front wall of the casing to engage the keeper. This latch bolt is normally retracted through the medium of an operating member 58 having an operating knob 59, with said member 58 rotatably mounted in the side wall of the casing in line with and being formed with a bore to slidably receive the end of the spindle 57. T he member 58 is connected with the latch bolt so as to retract the latter atwill upon turning of the knob 59, and the spindle 57 is provided with a laterally projecting pin 6l, which when the spindle is in position to operate the pinion 55, as hereinafter described, is adapted to engage one or the other of the serrat'ions 60 in the end of the latch operating member 58 to thereby cause said latch operating member to turn with the spindle.

The latch and adjacent wall of the casing are provided with openings to receive a removable pin 5l, which when inserted through the opening in the casing and taking into the latch bolt, prevents any movenient whatever of the latch bolt.

In operation assuming that the person desiring to open the lock is familiar with the various combinations required, the upper and lower sets of discs described will be arranged in their predetermined relative positions to so align the slots in the disc as to permit movement of the lock bolt 2l. The spindle 57 is then pressed inwardly against the tension of the spring 68 until the ele` ment 69 has been moved into the path of the projection 70 on the disc 56. Following this engagement, the spindle 70 is moved to a predetermined position governed Aby the dial, at which position the slot 72 in the disc 56 and the slot 7l in the pinion 55 will register. The spindle 57 is'then moved farther inwardly to cause the member 69 to enter the slots 72 and 7l, locking the pinion to the spindle 57. Turning movement of the spindle in the opposite direction will 'then obviously actuate the locking bolt 2l to withdraw the locking lugs 2O from the keeper. Vhen the spindle has been moved to pinion operating position, the pin 6l on such spindle will engage one of the serrations of the latch operating member 58, so that as the spindle is 'turned to operate the locking bolt, the latch will also be withdrawn. If, however, it is desired that the lock shall 'not be operated even with a knowledge of the combination, the pin 51 may be introduced into the latch, preventing movement of the latter, and as the locking bolt operating spindle cannot be turned without operating the latch, the Xing of the latch against movement prevents operation of the lock.

That I claim is:

l. ln a lock, a locking` bolt, independent sets ot tuinblers tor controllingthe movement ot said locking` bolt, an operating member tor the looking bolt, and means adapted to interlock with said member for operating the same, said means being` normally tree of the member and adapted to be positioned itor interlocking therewith in a predetermined relative arrangement ot the member and said means.

2. ln a combination lock, a casing, a lockingr bolt operative therein, tumblers for controlling the movement oi the locking' bolt, a pinion tor operating;` the locking bolt, and a spindle for operating the pinionA` said spindle being* normally tree ot' the pinion and adapted to interlock therewith in a predetern'iined relative arrangement of the parts.

In a combination lock, a casing, a loikingr bolt operative therein, tumblers for controlling the nlorement of the locking; bolt, a pinion tor operating` the locking' bolt, a spindle tor operating the pinion, said spindle being normally tree ot the pinion and adapted to interlock therewith in a predetcrn'iined relative arrangement ot the parts` a latch bolt mounted in the casing, means tor operating` the latch bolt, and a connection between said spindle and latch bolt operating means when the spindle is in operative relation with the pinion.

4. In a. combination lock, a casing, a locking' bolt operative therein, tumblers for controllingl the movement of the lockingbolt, a pinion tor operating the locking bolt, a spindle tor operating the pinion, said spindle being normally free ot the pinion and adapted to interlock therewith in a predetermined relat-ive arrangement of the parts, a latch bolt mounted in the casing,

means for operating the latch bolt, a connection between said spindle and latch bolt operating means when the spindle is in operative relation with the pinion, and means for locking the latch bolt against movement.

5. In a combination lock, a lock bolt, spaced sets ot tumblers for controlling the movement of the lock bolt, a pinion for operating the lock bolt and formed with a radial recess, a disc mounted in advance of the pinion and t'ormed with a similar recess, a spindle slidable axially ot the disc and pinion, and means whereby the spindle may operate the disc to align the slots in the disc and pinion, said spindle being,` longitudinally movable to permit the passage ot said disc operating element into the aligned slots of the disc and pinion, wherebyv to interlock the spindle and pinion to compel operative movement of the lock bolt in the movement ot the spindle` 6. A latch bolt, an operating` member therefor, a spindle on which the operatingr member is mounted, a locking' bolt, a pinion tor operating the locking bolt, said spindle being adapted to interlock with the pinion at will` and means on the spindle to interlock with the operating member ot the latch bolt when said spindle is in a position to interlock with the pinion.

T. latch bolt, an operating mem-ber therefor, a spindle on which the operating member is mounted, a locking bolt, a pinion tor operating the lockingl bolt, said spindle being` adapted to interlock with the pinion at will, means on the spindle to interlock with the operating` member of the latch bolt when said spindle is in a position to interlozrk with the pinion, and a pin to engage with the latch bolt to prevent movement thereof, whereby to lock the parts against operation.
